Add a global property for the Maven XML plugin in the tests module ------------------------------------------------------------------ Key: ELY-1789 URL: https://issues.jboss.org/browse/ELY-1789 Project: WildFly Elytron Issue Type: Task Components: Build Reporter: Justin Cook Assignee: Justin Cook Priority: Major Fix For: 1.9.0.CR4, 2.0.0.Alpha4 Currently the codehaus xml-maven-plugin property only gets defined in the tests module if the build JDK is at least JDK 9, resulting in a cryptic error message if building with a version less than JDK 9. This task is to add a global property for the plugin for the minimum JDK enforcer error message shows instead of a missing plugin version message.
